Players on the Dolphins, under review by the NFL, may have violated portions of the NFL's Personal Conduct Policy if allegations of harassment of offensive lineman Jonathan Martin and other allegations involving the treatment of younger players are proven true, according to league sources.

The NFL Personal Conduct policy imposes a standard of conduct for league and club employes, including players and coaches. That policy states employees of the NFL or a member clubs are "held to a higher standard and expected to conduct yourself in a way that is responsible, promotes the values upon which the League is based, and is lawful.

"Persons who fail to live up to this standard of conduct are guilty of conduct detrimental and subject to discipline, even where the conduct itself does not result in conviction of a crime."

Employees found in violation of the policy may have discipline imposed for any of the following circumstances:

• Violent or threatening behavior among employees, whether in or outside the workplace.

• Conduct that imposes inherent danger to the safety and well being of another person; and

• Conduct that undermines or puts at risk the integrity and reputation of the NFL, NFL clubs, or NFL players.

In recent days there have been numerous reports of alleged harassment or mistreatment or even "bullying" of Martin. That alleged bullying included Martin being the subject of a prank in the team's lunch room when other players invited him to have lunch with them. Martin, the story goes, sat down and his teammates all got up and left him alone at the table.

ESPN and CBSSports reported today that Dolphins guard Richie Incognito is one of the leaders of the alleged poor treatment of Martin and gave examples of the veteran guard's actions.

[Update: The Dolphins released a statement at approximately 4:30 Sunday saying, "We received notification today from Jonathan's representation about allegations of player misconduct. We are taking these allegations very seriously and plan to review the matter further. We have also reached out to the NFL and asked them to conduct an objective and thorough review. As an organization, we are committed to a culture of team-first accountability and respect for one another."]

The NFL is conducting a review on the matter which could lead to actions if it finds violations of the Personal Conduct Policy. The NFL Players Association is also not conducting a formal investigation.

And this issue is bound to become more complex before it gets resolved.

Part of the issue is that Martin, which the club maintains is ill, is now through representatives apparently offering details and naming names in incidents of misconduct. But, interestingly, the club is aware of at least one incident in which Martin participated in what could be construed as pranksterism or hazing or, bullying.

Earlier this year, members of the offensive line took guard Josh Samuda's car keys and moved the car from where Samuda had parked it. Martin, a club source confirmed today, was part of that prank.

Also, one source tells me that the same joke that apparently sent Martin over the proverbial edge -- the lunchroom prank in which players abandon one teammate -- was done to guard Nate Garner the week before.

And Martin was allegedly involved in helping to perpetrate that one.

Another layer and tangential to this story is the Dolphins embracing of rookie hazing. The NFL confirmed to me that rookie hazing does indeed fall under the NFL personal conduct policy. And so at the point where players are forced to shave or dye their hair, or carry gear for veterans, or pay for meals out or bring ordered meals on team flights for veterans, it all falls under the policy.
